This is an upgrade part for a Floyd Rose, made of stainless steel with a red metallic finish. It is compatible with Floyd Rose Original systems and likely not compatible with Gotoh-made ones. Unlike titanium parts on the market, which often have discoloration due to high heat, this appears to have a coating. It is almost unused, but the coating has chipped slightly during a test fitting. This is particularly noticeable on the screw threads, which is unavoidable. Due to this specification, it is cheaper than titanium versions, with a new price of around 15,000 yen for everything shown in the photos. While it has the disadvantage of being less resistant to wear than titanium, some might see this positively, as it could blend well with a well-used guitar.
